Explain why aluminium metal can displace copper from copper sulphate solution but copper cannot displace aluminium from aluminium sulphate solution ?

Explanation

To understand why aluminum can displace copper from copper sulfate solution while copper cannot displace aluminum from aluminum sulfate solution, we need to analyze the reactivity of these metals and their positions in the reactivity series.

### Step-by-Step Solution:

1. **Understanding Reactivity Series**: The reactivity series is a list of metals arranged in order of decreasing reactivity. Metals that are higher in the series can displace those that are lower from their compounds.

2. **Position of Metals**: In the reactivity series, aluminum (Al) is positioned above copper (Cu). This indicates that aluminum is more reactive than copper.
